what does cdr103 error mean?

“CDR103” isn’t a universal error code — it appears in several unrelated systems. To explain it accurately, I need to know where you’re seeing it.

Common places where CDR103 shows up:

• CDR (Call Detail Record) systems – often means a parsing error or missing/invalid field in a telecom CDR file.
• CDR software (CorelDRAW) – sometimes refers to a file-read or file-corruption issue.
• Medical/clinical reporting systems – can indicate a data import failure.
• Backup/restore or CD-recording tools – may mean media read error.

Could you tell me which application, device, or system is giving you CDR103?

Good question — if you get a “CDR103” error on a CD-ROM drive, it usually means that the disc in the drive is not in a supported format. Microsoft Support

✅ What CDR103 means

• Specifically, when using older DOS-era or early Windows drivers (like MSCDEX.EXE), “CDR103: Disc in drive is not High Sierra or ISO-9660 format” is the standard meaning. Microsoft Support
• In other words, the CD you inserted wasn’t laid out in a filesystem structure (CD “format”) the drive software can recognize. Microsoft Support

⚠️ Why it happens

• The CD may have been burned or mastered in a format incompatible with these older CD drivers (e.g. proprietary, non-ISO, audio-only, or for another OS). Epson Support Files
• Some older CD-ROM drives — especially certain high-speed or SCSI-based drives — had known compatibility issues with some disc formats or longer-than-standard discs. Microsoft Support

✅ What you can try to fix / work around it

• Try a different disc (especially one known to be formatted in standard ISO-9660).
• If the disc was burned by you: re-burn it using a standard ISO-9660 filesystem (i.e. classic “data CD” format).
• If possible, use a more modern CD-ROM drive or a modern OS — modern drives tend to support more formats and are more forgiving.

If you like — I can help you see if your disc can be “fixed” or made readable again (or check if the drive is just too old). If you tell me the disc type (audio / data / burned CD-R / commercial CD) and the drive model (if you know), I can walk you through some diagnostics.
